Ever since Chip Kelly took over as head coach of the Philadelphia Eagles in January, all we've been hearing about the offense and defense he will install is that it will be personnel-driven. As for the read-option on offense and a 3-4 base defense, he has refused to commit publicly.

All of that changes on Tuesday, when the new coach and almost entirely new staff will begin a three-day minicamp that only new head coaches are allowed to conduct before the NFL Draft, which begins on April 25.

Even if he closes the on-field workouts to the media, we will have a much better understanding by this time next week of what exactly it is he'll be running this first year. Furthermore, the coaches and general manager Howie Roseman hope to be able to finalize their draft strategy based on what they see from the guys they have now.

Don't let the "best available athlete" claims fool you. The Eagles did a few nice things in free agency, but not nearly enough after being burned by the process of pursuing many of the best available free agents the past two years.

They still have immediate needs (offensive line, defensive line, linebacker) and more questions than answers about fitting some of the seemingly square pegs (Brandon Graham, Trent Cole, Vinny Curry) they have into the round holes Kelly is expected to have when he attempts to upgrade the size and ability of his defense and increase the speed at which the offense will operate.

Oh yeah, almost forgot: Who's the quarterback?

Starting on Tuesday, we'll get a better idea of who fits where, who might not fit at all and what they have to do the following week to put a competitive product on the field in 2013.

These next two weeks will go a long way toward determining whether the Eagles have a chance to be good right away or whether they'll have to wait at least one more year to be a factor in the NFC East again.
